Recently brought one for 350k to combine with my winged scarab
Should i keep it or sell if for a multi blocker? I have a about 500k additional and only 1p battle and my stats are all kinda low
Combining a quick glance over the Opponents and my memory, water defense/reflection is viable against the following opponents: Chiazilla, Jelly Chia (early battle), Lady Frostbite, Snowager, Snow Faerie, Snow Beast, and Plumbeard.
Almost all of those are "big boy" opponents. From a general One Player standpoint (and from a Two Player standpoint, for that matter), Water defense is one of the weakest defenses. Given you're only doing One Player and that you probably aren't looking to max out against Jelly Chia or Lady Frostbite, sell it and spend the money on training.
